ST'ES TRAY FOR INCUBATORS AND BROODERS.

Application led February 3, 1921. Serial No. 442,125.

y To all whom t may concern.'

` that is provided with means for providing an even heat so that theeggs or chickens carried thereby will notbecome chilled under ordinaryconditions.

Another obj ect of the invention is the construction of a tray whichgathers and retains heat so that the chickens or eggs carried therebywill not readily become chilled, which means is also pro-vided forpreventing overheating the eggs or chickens.

With these and other objects in View, my invention comprises certainnovel combinations, constructions and arrangements of parts `as will behereinafter described, illustrated in the accompanying drawings, andmore particularly pointed out in the appended claim.v i

In the drawings:

Figure 1 is a top plan view of an incuhater constructed' in accordancewith the present invention.

Figure 2 is a View in side elevation of the incubator.

Figure 3 is a sectional view, taken on line 33, Fig. 1, and looking inthe direction of the arrows.

Figure 4 is an end view, in elevation, of the incubator, looking at theend to which the heating apparatus is connected.

Figure 5 is a sectional View, taken on line 5-5, Fig. 3, and looking inthe direction of the arrows.

Figure 6 is an enlarged fragmentary sectional view, taken on line 6 6,Fig. 1, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the body of theincubator, and 2 are the legs supporting they same. The body has aninner lining 3 spaced therefrom between which inner lining and the outerlining a compartment 4 is formed that may contain hot air but preferablyis for hot water.

The heating apparatus comprises a tank 5, into the central part of whichextends the chimney 6 of the lamp 7, and the tank 5 is connected by tube8 to the top of the body 1 and by the curved tube 9 to the body nearvits bottoni; these tubes 8 and 9 provide means for permitting water inthe tank and body of the incubator to circulate, while heated by thelamp 7.

A cap 10 is provided for iilling the compartment 4.

A. hollow hinged door 11- is formedupon the top. The front door 15 ishingedy upon the body 1 of the incubator and this door' has glass in thesame as usual, so that eggs can be easily seen upon the tray 16. Theyoung chicks can also be seen through the front door 15. y l' The tray`16 rests upon angular brackets 17, each bracket `being provided with ahorizontal foot 18. y

The tray 16 comprises a false bottom. 19, in which bottom viscompartment. 20, the compartment being Vi'illed by a liquid 0r water bythe removal` of the cap 21. A. strip of feltv 22 Vis placed upon thefalse bottom and the uppery section 23 of `the tray, containing' theeggs 24, is placed upon the felt 22; the false bottom, :telt `and uppersection or container 23 can be securely fastened'together by anysuitablev means. `The felt 22 prevents too much heat-'affecting the eggs24 and by reason of the closed bottom of the tray air is kept fromrushing up through the bottom and by the eggs, which would tend tounnecessarily cool them or harden the shell during incubation.

lt will be obvious that young chickens can remain on the tray 16,without injury, until the operator removes same by opening the door 15.

The means for controlling the temperature of the incubator comprises acoil thermostat 25 mounted upon lug 26 attached to the inner wall of theincubator, Fig. 6. The outer loo-p or coil of the thermostat terminatesin a vertical rod 27, which rod extends through the pipe 28 and abovethe top of the incubator, or broeder, as this thermostat and damperdevice is applicable to both the incubator and the broeder. The extendedupper end of the rod 27 is threaded and upon this threaded end are apair of nuts 29. Between these nuts 29 are the 10013 ends 30 of theflame cut-orf lever 31 and the damper lever 32. The levers 3l and 32 arepivotally mounted in the notched upper ends or angle brackets 33. Thedamper lever is connected, at its upper end, to the damper 34, whichdamper 34 closes the heat compartment 35 ot the tank 5.

The flame cut-ofi' lever 31 is provided with a vertical extension 36,Which extension 36 pivotally connected, at its lower end, to arm 37 ofthe rocking frame 38, which franie is of an open structure being formedof. Wire; the frame 38 is adapted to straddle or move over the Wick 39`of the lamp 7 and cut out or extinguish the flame, as shown byfdottedlines 40 in Fig. 3, when the temperature becomes too great in theincubator', causing the expansion of the thermQSf-af: 35 and the ShevnaupV the rod 37, thereby permitting the levers 3l and 32, at their outerends, to move downwardly, causing the closing of the damper 34 and theswinging of the rocking frame 38 to cut off or put out the 39. This willresult inthe stopping of the heating of the liquid in the tank,` but byreason of the damper 34 bein-g closed, the heat in the tank Will onlyslowly be given off, thereby retaining the heat in the Whole apparatus avery long time suliicient to allowr the operator to discover that the liht is `out or extin* gushed., 011 @limit the .lighting Of the lampbefore any arm has been done.

fAs Vhereinbleiifore indicated, my incubator @an be `@asili adapted .t0the use Of a broodel', by the Chickens remaining @n the tray 16, or byplacing in any suitable` floor o n the bracket 1.7 to keepi the chickensolf the inner (lining 3. I make no claim to the iviooring that wouldentirely the space and prevent the chickensfrom dropping ont@ the lining'3, but this eerine can be easily inserted in the body j., Withoutinvolving invention.

The pipe 4l extends through the side. of the body l, its inner endprojecting into the inner compartment of the body and its outer endextending beyond the outer surface of the body, so that the outeratmosphere Will enter the compartment, containing eggs or chicks,allowing the right degrec of moisture or a similar quantity of ire-shair to enter the chamber and thereby keeping the conditions in thechamber sanitary, the air being purified by the medium of the pipe 41.

While I have described the preterred structure of my apparatus,`an dhave illus Hated-"Phe Sain@ in the aeomraeyes dawi-y IleS, @erta-n minorChanges or ltelibens en be by one eine@ in the @e to which thisinvention relates., .in the manufacture of my apparatus on an enlargedscale and I, therefore, reserve the right to make such alterations orchanges as shall.
